The xhorse v2.0.1 cable 100% works with all modern Toyotas (K-line and CAN BUS) except you get no L line support for flashing ECUs. It will definitely no do. This is tested by most of Toyota owner, me included.

Firmware PCB Layouts, parts are well soldered and connected.

If you need, here is free TIS Tecshtream 10.10.018 software to load:

Buyer : I bought 2 mini vci j2534 cables with Tecshtream Ver. 10.10.018 CD last week from a site (worldobd2.com) claiming to be an authorized “Xhorse” dealer. That one works on both my 2002 Prius ISO9141 (with 22 pin connector) and a 2009 Camry Hybrid CANbus (with 16-pin diagnostic connector).

I used to buy one non- Xhorse Techstream cable, it worked too. But I failed to get it worked on K-line Toyota on Win 7 64-bit operating system. The second xhorse cable runs perfectly on Win XP, Win 7 32 bit/64 bit Virtual PC on Intel based laptops.
